About Cassette Tapes
[ Aboid the following types of tapes
• Cassette tapes exceeding 90 minutes
These tapes are handy for their long playback and recording
time but be careful about repeatedly stopping and starting,
rewinding and fast forwarding these tapes in short intervals as
they are thin, tend to stretch and may become entangled in the
machine.
• Fs-Cr tapes (TYPE m)
The high frequency range will be emphasized, and a flat fre¬
quency response characteristics cannot be obtained.
• Metai tape without detection holes in the cassette
Recordings will be very distorted. (There is no playback pro¬
blem, however.)
| Notes about the handling of cassettes |
If the tape in the cassette is loose, the tape can easily break dur¬
ing use or otherwise be damaged.
Never touch the tape itself, or attempt to pull it out of the
cassette.
Avoid tape storage in the following
place
Tapes can be damaged if it is stored in places such as described
below.
•Where the temperature is high (95°F/35°C or higher) or where
the humidity is high (80% or higher).
•Where there is a strong magnetic field (near a speaker, on top
of a TV, etc.).

Maintenance
Head care
To assure good sound quality for recording and playback, be sure
to clean the heads after approximately every to hours of use.
1) Press the open/close button to open the cassette holder.
2) Disconnect the AC power supply cord from the AC outlet.
3) Clean the heads, pinch roller and the capstan shaft of each
deck with a cotton swab (or with a soft, lint-free cloth) slightly
moistened with alcohol.
Do not use any solution other than alcohol for head cleaning.
Head demagnetization_
In order to maintain good sound quality during recording and
playback, it is recommended that the heads should be
demagnetized if distortion or poor sound quality persist after
cleaning the heads. If the heads become magnetized they could
create noise In recordings, loss of high-frequency response, or
erasure of valuable recordings. Several types of head
demagnetizers are available and may be purchased at local elec¬
tronics supply stores. Follow the instructions that are supplied
with the device.
•Do not bring any type of metal objects or tools such as
magnetic screwdrivers in contact with the head assembly.
